Looks like `NSWorkspace.shared.setIcon` can only be called from the main App, DockTilePlugin is sandboxed and doesn't have the permission to `file-write-finderinfo`.
It works fine in debug, but not in release. This fixes#11489, #11290
Fixes#11029 (probably)
If you renamed the app bundle, the prior check would infinite loop due
to the combination of two bugs: invalid termination checks and
hardcoding "Ghostty.app"
